16 Weeks, Sequential 2 Result: possible Down Syndrome?

UPDATE**

After 11 days (including non business days) I finally was wondering if I should seek out a number to call to see if the results were in and they’d forgotten to call me or something. I then remembered that my doctors office has an app where my lab results go and so I checked, and sure enough it was right there. I clicked and scrolled down, and it says that for all trisomies I have a less than 1 in 10,000 risk.

I have two theories, and it possibly might be a combination of both that caused my false positive result for the sequential.

I had recently that week switched from my prenatal to a regular women’s multi because my doc wanted me on something minus DHA because I have low platelets.

This multi had a high dose of biotin and biotin especially in higher doses, causes false positive on a multitude of blood tests! I found multiple links verifying this.

Also, I had preeclampsia with my previous pregnancy and what the sequential screens for Down syndrome his elevated levels of hcg and low plasma proteins, both of which I had. Those levels I had are also consistent with other women who end up developing preeclampsia in their pregnancies. With my history of preeclampsia though, I’m thinking if anything that this really showed me that I might have preeclampsia with this pregnancy too.

In all my research I noticed that other people going through similar situations to mine rarely returned to their posts with an update, so I wanted to make sure to update mine! Thanks for all your responses 😊

Also, I’m having a boy! 💙💙 we were happy either way, but we know our daughter will love having a little brother! Oddly enough, she already had been saying it was a baby brother for a while now 🤔

They called and gave me the news that the second part of my sequential showed a 1:72 risk of Down syndrome. They had me come in today, immediately, to draw blood for the cell free test (Natera).

I know 1:72 breaks down to a 1.38% and that’s actually really low. But I’m the type to assume the worst until I know better.

If this test comes back positive for Down syndrome being likely, my doctor could recommend an amnio. If the baby has DS then that’s that. It’s still my baby and I’ll love him/her with all my heart. Which is why I think I wouldn’t even want to even have the risks of an amnio. I’m a person prone to anxiety so not finding out would be really hard, but that’s a selfish reason to get one done. If I were to miscarry as a result, that’s something I’d drag myself to hell and back over risking just to find out if my baby has DS.

It’s still stressful and hard to not know and to have to wait. It’s going to be heartbreaking to know this baby if they do have DS could live a life of complications and illness.

My NPT ultrasound showed very low risk or chance of DS and the baby looked as it should without any markers. I’m 26 and don’t have any of the risk factors for carrying a DS baby, but it happens.

Has anyone else been through something similar, did you opt out or for the amnio and why, and how is your baby doing today?
